GAS-STOVE.

Application filed October 22, 1890.

' .Z'o ctZZ whom it may concern:

3e it known that I, PAUL J. GRINBERG, of New York city, New York, haveinvented an Improved Gas-Stove, of which the following is aspecification.

This invention relates to an improved gasstove, and more particularly toan improved construct-ion of the burner.

The invention consists in the various features of improvement more fullypointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical central section ofmy improved gasstove on line m 00, Fig. 2; Fig. 2, a top view thereof;Fig. 3, a bottom view of the annular disk Z1 of the burner, and Fig. 4 abottom view of cap 6 of the burner.

The letter a represents the annular frame of a gas-stove supported uponthe feet a and provided with four radial arms a that hold the disk I) ofthe burner. All these parts I prefer to cast in one piece. The disk I)is of annular form, Fig. 3, and it is made with a beveled upper edge band a beveled lower edge, Fig. 1. The beveled lower edge is providedwith a series of corrugations I). These corrugations extend radiallyfrom the inner edge of the disk toward the outer edge; but they are ofsuch length that a plain rim b is left around the corrugations, as 0shown. Against the lower beveled and corrugated edge of the disk I)there is placed the plain inclined flange c of a cup 0. This flange fitstightly against the corrugations, so as to form a series of radialdisconnected gasways.

The cup 0 constitutes in effect the gas-receiving chamber, it being madein one piece with a gas-receiving pipe 0 This pipe abuts at its free endagainst a shoulder a cast on frame a, to which it is held by the actionof a central bolt f, hereinafter described. The pipe 0 receives the gasfrom a cock (I, as usual.

Upon the plain upper beveled edge 11 of the disk I? there reststhe'beveled edge of a cap 6. This edge is provided with the radialcorrugations 6, similar in all respects to the corrugations b of disk Zthat is to say, the

Serial No. 368,913. (No model.)

corrugations extend from the inner edge of the cap to a point inside ofthe outer edge of the same, so as to leave the plain rim 6 around thecap. A central screw-boltf and a nutf on the screw-bolt hold the cap eand cup 0 tightly against the upper and lower beveled edges of disk I),and hold also the pipe 0 tightly against shoulder a". Thus it will beseen that the stove is made up of a very small numberof pieces and thatall these pieces are assembled by a single screw-bolt.

The gas flows from chamber 0 in an inclined direction upward to form anouter and an inner concentric flame. The gas that feeds the outer flameflows between the corrugations Z) and the flange c, and joins at theouter termination of the corrugations beneath the plain flange h The gasthat feeds the inner flame flows between the corrugations e and theflange b and joins at the outer termination of the corrugations beneaththe plain flange e The advantage of my improved burner lies in its greatsimplicity and also in the manner in which it subdivides and reunitesthe gas, so as to cause its thorough combustion.

\Vhat I claim isl. The combination of a gas-stove frame with an annulardisk Z), having beveled edges and radial gas-channels, and with a cap eand a cup 0, fitting against such edges, substantially as specified.

2. The combination, in a gas-stove, of the annular disk D,having'beveled edges, radial corrugations b, and plain rim W, with a cap0, having radial corrugations e and plain rim c and with a cup 0,substantiallyas specified.

3. The combination of the annular frame a with radial arms a an annulargrooved disk I), secured to such arms, a grooved cap e and cup 0,fitting against the disk, and a central screw-bolt f for connecting theparts, substantially as specified.

4:- The combination of an annular frame a with' radial arms a an annulargrooved disk 19, secured to such arms, a grooved cap e and cup 0,fitting against the disk, a gas-pipe 0 secured to cup 0, a shoulder aagainst which the gas-pipe abuts, and a screwJuolt f, to the cup, and :1central screw-bolt passing passingthroughthe capandeup,substantiallythrough the cap and cup, substantially as .[o

as specified. specified.

5. The combination of frame a, having T 1 i P1 I Q. Rik In 5 radial armsa with an annular g'i'ooi'ed disk 1 U1 G L I I, held by such arms andhaving inclined upper and lower edges,:i cap and acup fitted againstsuch edges, a gas-pipe connected Witnesses: F. v. BRIESEN,
